✦ Synopsis

The reactions of Ci3P=N-P(0)C12 (1) with primary and secondary amines have been studied. The following monophosphazenes, (RRV),P= N-P(O)(NRR),, and bis(phosphinoyl)amines, [(RRN),P(O)],NH were isolated: NRR = NHCH2Ph, NEt,, NH(CH2),CH3 groups for monophosphazenes, and NEt,, NH(CH2),CH3 for phosphinoyl arnines. The unexpected geminal phosphazene, Cl(RIW),P= N-P(O)Cl,, (RIW = N[CH(CH3)?I2}, was also obtained in moderate yield. The spectral data (ZR, ' H , C , and 3iP N M R , and M S ) are presented. The structure of 1 -(dichlorophosphinyl)-2-chloro-2,2-bis(diisopro-py1amino)phosphazene (5) was determined by X-ray crystallography. The basicities of these and related compounds in nonaqueous nitrobenzene solution were obtained bv potentiometric titration.
